The acpica_ddi_setwake (possibly on nge0) message is benign. If it
is associated with nge, then it means that wake on lan won't work for
that interface.
Mostly what we are saying is that sometime after the nvidia driver
is suspended, something else goes wrong, but as the display is
suspended, you won't see the message.

There is, but you have to open the box and plug in a serial port
connector to a 10pin header. In theory, a USB port could also be
used, but it's output will stop once the USB driver is suspended.
The serial port (i.e. ttya, com1, etc.) is setup to display messages
nearly to the _S3 call, and early on in wakeup. I am trying to see if
I can dig up how to do this on a U20 (don't have one handy).
